; The same vararg calling convention is used for ilp32/ilp32f/ilp32d and for
; lp64/lp64f/lp64d. Different CHECK lines are required due to slight
; codegen differences due to the way the f64 load operations are lowered and
; because the PseudoCALL specifies the calling  convention.
; The nounwind attribute is omitted for some of the tests, to check that CFI
; directives are correctly generated.

; Although frontends are recommended to not generate va_arg due to the lack of
